Description
Technical Field

Background
The face including mouth, nose, etc. is not only an important pathogen transmission port, but also a part which is easy to invade by pathogens, and the face is the key point for isolation and protection in clinical diagnosis and treatment, public health and occupational protection. The purpose of its use is to prevent environmental pollution and reduce the risk of infection of personnel, especially for infectious diseases. The current facial isolation devices include fixed shape oronasal masks and fabric structured masks. However, the existing oronasal mask and the existing mask have two important defects, so that the mask cannot play a role in isolation and protection in some application scenes and high-risk operation.
The first important defect of current oronasal mask and gauze mask is that do not possess the function of cooperation mouth opening action, and mouth opening action both is human common physiology action, also is the conventional action of diagnosing that needs patient's complex in the clinical diagnosis and treatment, and current isolating device is the modular construction, can not adapt to a mouth motion, can't wear current gauze mask or oronasal mask when carrying out corresponding operation of diagnosing, causes the high risk to expose, has very big infection hidden danger in practical application. If the epidemic situation occurs, the existing mask or oronasal mask cannot be worn when the operations of throat swab or endoscopic examination, which require mouth opening of a patient, are performed, meanwhile, the exposure risk of the clinical diagnosis and treatment operations is extremely high, cough of the patient or outflow nasal secretion of the patient is easily caused, and a large amount of droplets containing pathogenic microorganisms can be scattered by mouth opening action, so that the environment is easily polluted and the disease transmission is easily caused.
A second drawback of existing oronasal masks or oral masks is the inability to accommodate different operational pathways for clinical treatment. When the mouth and nose part is diagnosed, medical instruments with different shapes are required to pass through the oral or nasal cavity to complete the operation, and the position is required to be continuously moved during the operation so as to perfectly realize the diagnosis effect. The existing isolation device is not provided with an external access or is fixed in position of the external access, so that diagnosis and treatment operations of the mouth and nose are limited, due effects are difficult to achieve, in an actual clinical scene, multiple clinical operations are often required to be performed on the same patient, for example, when a patient needs to perform oral sputum suction nursing and nasal cavity intubation at the same time, and implementation paths of different diagnosis and treatment have great difference, and the isolation device worn by the patient is usually required to be taken down. The existing mouth-nose mask or mouth mask has an obvious defect period, the uninterrupted isolation and protection effect is difficult to realize, if a patient has infectivity, the environment pollution or the infection of others is easily caused in the isolation defect period.
